Reply To: OSSC Sync issues specific to AV1


Everything I’ve thrown at it from the PS1 or PS2 shows up as 525i/263p

That’s correct, OSSC LCD shows the entire signal including non-visible parts, though PAL signal should be different.

Interlaced content doesn’t deinterlace amazingly,

OSSC is a line doubler, it doesn’t have a frame buffer so cannot perform sophisticated deinterlacing.
